gene interactions
recognise the phenotype ratios on sight, a bit dangerous to memorise them without reading the example right through.Epistasis means masking.

| A | B |
|---|
| 9:3:3;1 no interaction | mendel dihybrid cross |
| 9:3:3;1 phenotypes new combinations | collaboration |
| 9:7 final phenotype needs both genes | complementary, epistasis |
| 9:4:3 one gene masks expression of other | supplementary , epistasis |
| 1:4:6:4:1 | polygenes |
| 2:1 one phenotype missing | lethal genes |
| 3:1 one characteristic | mendel monohybrid |
| 1:2:1 a blend occurs | incomplete dominance |
| no ratio no blend | codominance |
